getRole

public ObjectPropertyExpression getRole()

getLength

public int getLength()

Description copied from interface: KBElement

Gets the length of this knowledge base element. For instance, A AND B should have length 3 (as three constructs are involved). There are different ways to define the length of an axiom, class description etc., but this method provides a straightforward definition of it.

Returns:

The syntactic length of the KB element, defined as the number of syntactic constructs not including brackets.
